ZN091-ZIL.GL.V5P1 ZIEHL-ABEGG 910mm ZAplus EC Axial Fan

Description

The ZIEHL-ABEGG ZN091-ZIL.GL.V5P1 is a premium industrial EC axial fan from the ZAplus high-efficiency system, featuring a 910 mm impeller. It is powered by the advanced ECblue motor technology (Size MK152), designed for 3-phase 380-480 V AC operation. The ZAplus system integrates a bionic blade design (FE2owlet) with a high-strength, UV-stabilized composite nozzle and diffuser, which significantly increases pressure recovery while minimizing acoustic emissions. This fan is the global benchmark for high-performance cooling in data center chillers, massive air-cooled condensers, and industrial heat exchangers where maximum energy efficiency and intelligent MODBUS communication are required.

Application
The ZIEHL-ABEGG ZN091-ZIL.GL.V5P1 is the flagship thermal solution for mission-critical industrial cooling. Its FE2owlet blades, inspired by the silent flight of an owl, feature serrated trailing edges to drastically reduce turbulence and acoustic noise. The ZAplus housing acts as a multi-functional diffuser, converting air velocity into static pressure, which allows the fan to operate at significantly higher efficiencies in high-resistance environments like V-shaped condensers and large-scale dry coolers. The ECblue motor provides full intelligence with a built-in MODBUS interface, enabling seamless integration into Building Management Systems (BMS) for real-time monitoring of power consumption, motor temperature, and operating hours. Its robust IP55 rating and high-performance composite frame ensure unmatched reliability for outdoor rooftop installations in harsh climates.
